Relationship between the number of taxa sampled and MNTD in Neotropical regions for four emblematic Amazonian tree genera. Regions are numbered following Fig. 1. The solid black line represents the mean null expectation for MNTD given the number of taxa sampled for 1,000 random draws of that number of taxa from the phylogenies. The shaded gray area denotes the 95% confidence intervals of the null expectation for that relationship. Regions that fall outside of the 95% confidence intervals are labeled.
